Also, try your old body on the new kit, to eliminate that entirely from the heat equation. You will need to open the front of the old body up a little for the new ackerman though. I'm also going to be trying to fit a 14t, but for my 2100kv SMC motor.
As for the reason, this all spins the center shaft less quickly, which means the rotating mass down the center is less of a drag on the motor, and therefor more efficient if the rest of the system is the same in efficiency as before.
